Transmission Rebuild Kit - Seal Help

[t6dpilot]

I recently rebuilt a 901 transmission with a custom gear setup and am getting ready to install it in my car. I used up almost all the seals in the kit from Stoddard, but have these two left over and want to verify where they go. The larger O-ring looks to be the speedo drive seal and seems to fit there. It is 30mm OD and a knowledgeable source believes that this is correct. Can someone here confirm this?

The second seal is about 18mm OD and I do not have a clue where it goes. Any help? Ed....? Thanks.

Scott, that radial seal is probably the shift rod seal in the nose cone, sounds like about the right size.

Thanks Ed. That seal is too small for the shift rod. Plus I also replaced it. It looks just the same but smaller. Do you agree that the larger o ring is for the speedo drive?

Scott, if it's too small for the shift rod, other place it could be used would be within the speedo drive. The o-ring should be right for the outer seal of the speedo drive, the radial seal is inside.
